O uso de blogs e aulas experimentais como práticas educativas no ensino de físico-química para o ensino médio : um estudo descritivo a partir do conceito de aprendizagem significativa

Abstract

The use of differentiated teaching methods has become increasingly necessary for the demands of society. Information circulates every day more quickly and efficiently; and the school, as a space of knowledge construction, must be prepared to provide the student with skills and abilities which are relevant to the use of new technologies and also to the recognition of scientific phenomena within daily facts, another important skill to be developed. This work aimed to analyze the use and acceptance of blogs and experimental classes as pedagogical tools in the teaching of Physical Chemistry, in the light of significant learning. The research was anchored in the meaningful learning theory of Ausubel (1978), the concepts of assessment of learning by Luckesi (2008) and the constructionist proposal of Valente (1993). The research developed was descriptive and bibliographical in nature, of experimental model and with case study developed in field, following a quali-quantitative approach held with students of 2nd year of high school enrolled in a state education system. Students were divided in groups, one of which had Chemistry classes where the teacher used traditional methods, while the other groups had access to a blog create especially for the development of this work, as well as experimental classes in the Science Lab, making use of experiments from their daily lives. The results showed that the deployment of differentiated classes by the use of the blog and of the experimental classes is able to arouse the curiosity of students and may facilitate the search for knowledge. However, the professional in education must be prepared to choose the best teaching strategy, according to the social and economic possibilities of the school.
